Applicationfiled July 15, 1921; Seria1,No. 484,993.

To all whom it maywconcewt:

Be it known that I SAM EL "V. GCRONiA, a citizen of the Unitedstates,residing at Janesville, in the countywof'Rock and State of WVisconsin,have invented new-and useful Improvements ln-Fountaln. Pens, of

whichwthe following isa specificationu,

This invention relates to fountain .pens' and more particularlyutofountain pens of the self-filling type. I

Anobject ofthe invention "ifs-to provide a self-filling fountainpenwhich isfsim'ple in construction and does not embody any protrudingstructures necessaryin'the op-" eration of the filling mechanism as wellas one in which the'operati'ng structure for the filling mechanism isconveniently located to be easily and" quickly operatedwithout requiringthe removal of any caps," the movement of any levers oranalogousstructures. f r

More specifically the invention comprehendsthe provisionof a selffilling fountain pen wherein the fillingor emptying operation isperformed by the rotation of a button or cap carried at one end of thebarrel of the pen body, the saidbutton or.

cap serving to operate a pair of cams which in turn contract the 111kcarrying bag for 30 creating a suction upon theexpansionof the bag fordrawing ink 'thereinto. I Other objects of the invention will apk pearin the following detailed description and inthe accompanying drawingwherein: Fig. 1 is an elevation of the improved fountain pen without theclosing cap.

Fig. 2 is a fragmentary longitudinal sec carrying bag 5. As is usual inself-filling fountain pen structures the ink carrying bag 5 is formed ofsoft rubber and after it has been collapsed the suction created by itsexpanding or reflexing action will draw the usual manner through thepoint 6. .111 the present invention the barrel 1 has ink .thereintowhich ink is dispensed a. the

an inwardly extending flange??? at its end remote from the pen carryingend thereof. A ferrule 8: is inserted through the reduced opening in 1the barrel 1 formed the flange-7 and it is provided withY-anroutwardlyextending flange 9 which engages against; the innerend of theflange 7 as] clearly shown linFigure f the drawing.

The ferrule '8 extends" into the'sleeve 10) which is provided with. anannular inwardlyiextending flange l'l'forming a shoulder 12against whichthe annular flange 13 of r the V. ferrule 8 enga es for connecting thesleeve 10 to the'bo y 1 to-perniit rotation of the sleeve 10relativetothe body. In as sembling the pen, the flange 13" is spun onthe ferrule 8 after it is placed in position.

A cap 14 is threadably connectedto the 81681610 and it carries acam 15The cam 15 is rigidly mounted in the-"cap l t'and has its inner endbeveled .in both directi'ons-towards'its 1 center as clearly shown at16' forming a wedge-shaped end' which. ex-

tends into a correspondingly recessed end 17 of the longitudinallymovable cam 18. The cam 18 has. a radial lug 19 thereon which extendsinto; a recess 20 formed. in the sleevev 8 to prevent rotation of thecam 18 but permit it tomove longitudinally in tl1e'sleeve8, the sleevebeing fixed against rotation. -The outer end" of the cam 18 is recessedand receives thereinthe end 21 of V the spring 22. The flat spring'22extends longitudinally in the; barrel and, its end remotefrom the end 21is engaged between the ink bag 5 and the barrel 1 adjacent the head 4 ofthe ink bag. A bag compressing strip 23 is carried by the spring. 22being connected thereto by suitable rivets 24: in-

termediate the ends uf the spring and'strip. When the cap .14 is rotatedthe bevel end portlon 16 of the cam 15 riding over the bevel recessedends of the cam 18 will move the cam 18 outwardly or towardsth-e ink bag5, bowing the spring 22as shown in dotted'lines in Fig. 2 of thedrawing,'and forcing the strip 23 towards the axis ofthe barrel 1which'will compress the ink bag 5.

The foregoing operation willbe provided in the first half rotation ofthe cap '14: and the second half of the rotation of the cap will movethebeveled ends of the cams into. i

inventionnnay be constructed. in various re istration or en a ementermittin the 23 b b O spring 22 to assume its normal position the use'ofremovable caps, projecting parts, or the like is eliminated except thoseactu-- ally used in the filling ofthe pen. It is, of course, to beunderstood that the other manners and the parts associated in differentrelations and, therefore, I do not desire to be limited in any mannerexcept as set forth in the claims hereunto appended.

Having thus described my invention what I claiinis: M E

1. In a self fil ing fountain pen, a barrel,

a sleeve, a ferrule connecting said sleeve andbarrel to permit rotarymovement of the sleeve, an lnk bag, means for coinpresslng said ink bag,a'longitudinally movable cam carried by said ferrule, ,a second camrotatable with said sleeve and engaging said first named cam foroperating said bag compressing means.

2. In a self filling fountain pen, a barrel, a closure for the butt. endof the barrel, a ferrule connecting said closure and barrel to permitrotary movement of the closure relative to the barrel, an ink bag, meansfor compressing said ink bag, a longitudinally movable cam carried bysaid ferrule,

and a second cam rotatable with said closure and engaging said firstnamed cam for operating saidbag compressing means. 3. In a self fillingfountain pen, a barrel, a closure for the butt end of said barrel, aferrule connecting said closure and barrel to permitrotary movement ofthe closure relative tothe barrel, an ink bag, means for compressingsaid ink bag, a longitudinally movable .cam carried by the ferrule,

and means rotatable with said closure and engaging said cam foroperating said bag compressing means.

4; In a selffilling fountain pen, a barrel, a'closure for the butt endof said barrel comprising a sleeve, a cap connected to said sleeveforrotary movement with the sleeve, a ferrule connecting said closure andsaid barrel to permit rotary movement of the closure relative to thebarrel, a cam carried by said cap, an ink bag, means for comressin saidinkba and means carried by said ferrule and engaging said cam foroperating said bag compresslng means.

In testimony whereof I affiX my signature.
